How To Use Device Administrator - Samsung Galaxy S5

Learn how to use Device Administrator on your Samsung Galaxy S5. The Device Administration feature allows you to select one or more administration applications that control your device for security purposes (for example, if your phone is lost of stolen). These applications enforce remote or local device security policies.

Some of the features a device administration application might control are:

  • Setting the number of failed password attempts before the device is restored to factory settings.
  • Automatically locking the device.
  • Restoring factory settings on the device.

Note: If a device uses multiple enabled administration applications, the strictest policy is enforced.

  • From the main Settings screen, tap Security icon.
  • Tap Device administrators.
  • Select a device administrator and follow the prompts. If no device administrators are listed, you can download them from the Play Store.

Unknown sources

This feature allows you to download and install non-Market applications.

  • From the main Settings screen, tap Security icon.
  • Tap Unknown sources. A check mark is displayed to indicate it is active.

Note: Enabling this option causes your phone and personal data to be more vulnerable to attack by applications from unknown sources.

Verify apps

This feature allows you to either block or warn you before installing apps that may cause harm to your phone.

  • From the main Settings screen, tap Security icon.
  • Tap Verify apps. A check mark is displayed to indicate it is active.

Security policy updates

When you activate this feature, your phone will automatically check for changes to the security policy and download any updates to improve security and service.

  • From the main Settings screen, tap Security icon.
  • Tap Security policy updates to create a checkmark and activate the feature.

Send security reports

When you activate this feature, your phone will automatically send security reports to Samsung via Wi-Fi for threat analysis.

  • From the main Settings screen, tap Security icon.
  • Tap Send security reports to create a checkmark and activate the feature.

Storage type

This option allows you to select where you will back up your credentials.

  • From the main Settings screen, tap Security icon > Storage type.
  • Select the backup storage location for your credentials.

Trusted Credentials

If a certificate authority (CA) certificate gets compromised or for some other reason you do not trust it, you can disable or remove it.

From the main Settings screen, tap Security icon.
Tap Trusted credentials. The trusted credentials screen has two tabs:

  • System: Displays CA certificates that are permanently installed in the ROM of your device.
  • User: Displays any CA certificates that you installed, for example, in the process of installing a client certificate.

Tap a CA certificate to examine its details. A scrolling screen displays the details.
Scroll to the bottom of the details screen and tap Turn off to disable a System certificate or Remove to remove a User certificate.

Note:

When you disable a system CA certificate, the Turn off button changes to Turn on, so you can enable the certificate again, if necessary. When you remove a user-installed CA certificate, it is permanently deleted and must be re-installed, if needed.

  • Tap OK to return to the certificate list. When enabled, a check mark appears in the check box.

Install from phone storage

Install encrypted certificates from an installed memory card.

Note: You must have installed a memory card containing encrypted certificates to use this feature.

  • From the main Settings screen, tap Security icon.
  • Tap Install from phone storage, then choose a certificate and follow the prompts to install.

Clear credentials

Clear stored credentials.

Note: This setting only appears if you have installed encrypted certificates.

  • From the main Settings screen, tap Security icon.
  • Tap Clear credentials to remove all certificates.
